System Is On: I Deliver Express to the Underworld

My name is Jiang Zicheng, and I am a high school student. In order to take care of my mother who has cancer, I decided to drop out of school and find a job to support my family. By chance, I met Ling Xiao, who is the same age as me. Later, he introduced me to work for a courier company called Su Ming Express. There is a professional title for those in our industry. "Underworld courier" said that I deliver couriers rather than taking my own life, because... I only deliver couriers to the dead! This novel and its characters are purely fictitious.
